A woman with amnesia has turned to the Internet hoping someone can identify her after a large tumor left her without memories of family and friends.

ABC News reported that the woman -- called “Sam” -- was found in Carlsbad, California, by firefighters in February. It was unclear what she was doing when she was found.

According to the Facebook page created to help her find her family, “Sam” was immediately taken to a local hospital, where she was diagnosed with ovarian cancer.

Doctors told her that she had a volleyball-sized ovarian tumor and determined that she needed immediate treatment.

According to her Facebook page, “Sam” had to have emergency surgery to remove the tumor and some surrounding organs to help save her life.

Doctors also told “Sam” the tumor may have left her with few memories of her earlier life, according to the page.

"The amnesia I have is called retro amnesia and doctors have seen this before with the kind of antibodies that were found on the volleyball-sized tumor that was on my ovary," Sam said on her Facebook page. “The doctors said it could have been growing for 5 years causing me to be forgetful of things."

According to Interpol, “Sam” appears to be in her early 50s and speaks both English and French.

ABC News reported that she is described as being 5 feet, 7 inches tall, with white hair and brown eyes. She was found wearing a navy blue T-shirt with the words "Annapolis Harbor," blue shorts and Sperry boat shoes.

A spokesman for the FBI confirmed to ABC News Tuesday that agents at the local San Diego office were assisting law enforcement authorities in the search for “Sam’s” family.

ABC News reported that authorities are concentrating on contacts in Australia, since “Sam” appears to have an Australian accent and said that she dreamed of the country.

“All of my initial dreams had to do with a lap pool swimming in a salt water pool in Perth, then Icebergs in New South Wales and in Cairns in Queensland and Byron Bay,” she wrote on Facebook. “I also had many dreams of Hawaii living in a contemporary home there. Both Australia and Hawaii are extremely familiar to me.”

“Sam” also wrote that she had memories of being aboard a boat for months, explaining it was “not a cruise ship but smaller boat with a crew.”

Dr. Alan Lerner, director of the Brain Health and Memory Center at University Hospitals Case Medical Center, told ABC News that ovarian tumors have been known in rare cases to cause memory loss or psychiatric problems for patients due to anti-bodies or proteins produced by the tumor.

“[Proteins] can bind to the cells in the brain in areas that are important in memory,” said Lerner.

Lerner -- who did not treat the woman -- said even after treatment, the proteins can leave behind lasting damage, according to ABC News.

Sam wrote on her Facebook page that she has been out of the hospital for three weeks and is now receiving continued treatments to fight her cancer.

“I have been getting chemotherapy treatments and have lost all of my hair,” she wrote. “My prognosis is not good and I pray my family will be found soon.”

“Sam” also wrote that she is thankful for the medical staff and others who have stepped up to help her in the last few months.

“She has had an amazing positive influence upon many she has encountered during her lengthy stay in the hospital as a cancer patient,” a chaplain from the unidentified hospital wrote on Sam’s Facebook page.
